In installations of the present tvpei'thedoor "construction issiich thatco'nventionalregulator mechanism can not 'be employed. 'As indicated inFigiire 3 "the dom nates 9 and! o areeurved, so that the major portionof each lie's er itirely outside of the plane of movement of the windowpanel. It will be noted also that the plane of motion of the sector gear26 and arm 2| lies parallel to the direction of movement of the window.Thus it is necessary to provide suitable operating mechanism includingan operating crank, indicated in broken lines at 30 (Figures 2 and 3),operable in a plane of rotation which is substantially parallel with theinner door panel.

In order to accomplish this a drive shaft 3| is supported in aconventional friction clutch device 32 secured to the mounting plate 25in a position permitting a drive pinion 33 carried by the shaft 3| toengage gear teeth Ed on the sector member 26. It should be noted thatthe drive pinion 33 is in an intermediate position of an imaginaryquadrant, the lower line of which is horizontal and passes through theaxis of the stud 21. This upper position of the drive pinion isimportant so that the operating handle on the inside of the door is in aposition convenient to the operator.

Referring to Figures 3 and 4, the broken line A indicates a horizontalbase plane passing through the normal center of the drive pinion 63 andlies at a right angle to the plane of rotation. of the gear 26 (Figure2). The line B indicates the angle of inclination of the shaft 3! alongthe vertical line C of Figure 4 to place the shaft substantially normalor at right angles to the surface of inner door panel. This positioningof the shaft and pinion 33 requires the rim portion 26 of the gearsector 26 hearing the teeth to be dished or inclined normal to the lineB to facilitate engagement of the gear teeth and pinion.

Since the vertical plane indicated by line C is not in alignment with aline 35 (Figure 4) passing through the respective centers of the sector25 and pinion 33, the teeth of the pinion are formed helically toaccommodate their angular relation. This assures positive drivingengagement between the pinion and sector gear.

Figures -5 to 8 show diagrammatically the relative positions of theoperating parts of the regulator mechanism and the relation of thehandle shaft 35 and handle crank 36 to the inside door panel. In Figure5, it will be observed that the operating shaft 3! inclines straightupwardly and that the teeth of the pinion 33 properly mesh with theteeth of the dished rim 26' of the sector 26. In Figure 6, it will benoted that the handle crank 36 can be freely rocked without interferingwith the inside door panel 9 and the shaft 35 inclines upwardly from thehelical pinion 33. ihe proper meshing between the pinion and gear sectorteeth is shown in Figure 8. Figure 7 shows the freedom afforded thehandle crank 3% to rotate on the inside of the panel 9.

By way of contrast, reference is made to Figures 9 to 12 which show thesame parts as cle-= scribed above and in corresponding positions, theonly difference being that the gear sector is flat throughout and is notprovided with the dished rim portion. The same reference numbers areused but with the exponent a. lhe differences are apparent. The teeth ofthe pinion 33a do not mesh properly with the teeth of the The abovegraphically shows advantages gained by dishing the sector rim and usingthe helically toothed pinion, particularly in the illustrated locationof the pinion. In fact, where the pinion is raised above a horizontalline passing through the operating sector axis, it is necessary thatboth dishing of the sector rim and the use of the helical pinion beemployed.

This application constitutes a continuation of my application Serial No.587,761, filed April 11, 1945, and entitled Window Regulator DriveMechanism, now abandoned.

While I have shown and described one embodiment of the invention whichis the best form known to me at this time, it is to be understood thatnumerous changes in details of construction, arrangement and operationmay be effected without departing from the spirit of the inventionespecially as defined in the appended claim.

What I claim is:

In a vehicle having a window well, a window movable in and cut of saidwell to and from a closed position, an inside panel at the inner side ofthe well disposed out of parallelism to the plane of window travel,regulator mechanism for operating said window, said regulator mechanismcomprising a window engaging arm, a pivotal mounting for one end of saidarm disposed at substantially right angles to the plane of windowtravel, a gear sector for actuating said arm having a body portionsubstantially parallel to the plane of Window travel, a pivotal mountingfor said gear sector, the teeth of said sector being inclined laterallyrelative to said sector body portion and out of parallel relation to theplane of window travel, a driving pinion for said gear sector, saidpinion being disposed intermediate the ends of a quadrant, having alower end which is horizontal and passing through the axis of saidpivotal mounting, and having an upper end which is vertical and passingthrough the axis of said pivotal mounting helical teeth on said drivingpinion meshing with the sector teeth, those teeth of the pinion inengagement with the teeth of the sector being normal thereto, a shaftcoaxial with said pinion disposed at substantially right angles to andprojecting through the inside panel, said shaft inclining upwardly fromsaid driving pinion, and a crank handle on said shaft on the inner sideof the inside panel and rotatable in a plane parallel to the insidepanel.
